摘要: The traditional wideband digital channelized receiver in electronic warfare has problems of large amount data, occupying too much computing resources and complex realization. In order to solve these problems, an optimization design method for channelization based on high processing rate is proposed. Firstly the mathematical model with arbitrary oversampling factor derived theoretically, appropriate chosen establish polyphase architecture. Secondly filter bank optimized run at higher all operations are designed work same rate. proposed successfully implemented hardware, result shows that correct easy implement. Additionally its speed fast saved as well.
